Toward the selection of an enterprise architecture model for a cloud environment

Year 2012 celebrates the 25^th anniversary of Enterprise Architecture (EA) field, since in 1987 J.A. Zachman wrote an article entitled “A Framework for Information System Architecture” [10] which emphasized the role of a disciplined approach to the management of the information systems in order to achieve the success of a business. Due to capacity and scalability constraints, enterprises have to consider alternative architectures to support their day to day operations. This commonly implies a business model reengineering. Business model reengineering is a tough job, stakeholders have to accept and enact change. Only organizations that respond well and quick to change will be able to survive in the current business environment and economic climate. In this paper, we focus on two well-known Enterprise Architecture Frameworks (TOGAF and PEAF). First, we make a brief presentation of these frameworks. Second, we present a case study for the TOGAF EA and in the end we draw some conclusions.
